Brian Cox and Robin Ince look back at Planet Earth from the unique perspective of space with the help of astronauts Nicole Stott and Chris Hadfield, Space scientist Carolyn Porco and comedian and author Katy Brand. What can we learn about our own planet by looking back at it from space? The panel talk about the emotional response of looking back on earth, either from the ISS or via amazing photographs like Voyager's Pale Blue Dot, and the importance of realising our own place and significance in the vast cosmos.
